Description

Customizable modules

[0001] The present invention relates to a customizable module, and more particularly, to a module that forms a polyhedral vent and can be customized into a desired shape.

[0002]

[0003] Casts, plaster casts, splints, braces, corrective devices, and other medical corrective devices that enable smooth treatment when a joint or limb is fractured or damaged are collectively called casts.

[0004] Casts for immobilizing injured joints or limbs typically involve bandages and plaster casts. However, these casts are not only heavy, but cannot be reshaped once set. They also deteriorate or become damaged when exposed to moisture, making bathing or showering difficult for patients. Furthermore, the area where the cast is placed is not easily ventilated.

[0005] Examples of casts with a structure that is less prone to damage and allows easy air circulation include the hydraulic cast disclosed in U.S. Patent No. 6,673,029 and the hydraulic cast disclosed in Korean Patent No. 10-1425883.

[0006] However, the above-mentioned hydraulic cast has low productivity because it must be prevented from contact with water or moisture during the manufacturing process, and because it must be kept sealed to prevent contact with moisture even after manufacturing, there is a problem with storage. In addition, because it cannot be reused once it has been hardened, there is a problem in that it cannot be modified or reused even if the cast needs to be modified depending on the patient's degree of recovery.

[0007] To solve these problems, a cast having sufficient strength was completed through a thermoplastic cast including a core material in Korean Patent Publication Nos. 10-1414493 and 10-1538642.

[0008] In addition, in Korean Patent Publication Nos. 10-1538644 and 10-1538645, a soft outer skin is provided on the outer surface of the structure, thereby functioning as a reinforcing material and deformation-limiting element for the structure, and the patient does not feel discomfort even when the cast surface comes into contact with the skin.

[0009] However, the prior art has a problem in that when external force is concentrated on a specific part, the structure of that specific part is damaged.

[0010]

[0011] The present invention is intended to solve the above problems, and to provide a customizable module that solves the problem of damage even when external force is concentrated on a specific part.

[0012] In addition, the present invention aims to provide a customizable module that can prevent excessive deformation of the corner region of the outer skin defining the ventilation hole of a polyhedron and reduce external force.

[0013]

[0014] The problems to be solved by the present invention are not limited to the problems described above, and problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention pertains from this specification and the attached drawings.

[0015]

[0016] A customizable module according to one embodiment of the present invention may include a structure that forms a polyhedral vent and is customizable through shape deformation of the vent, the structure having a mesh shape and resisting external force to maintain its shape; an outer shell made of an elastic material that surrounds the structure to form the vent and minimizes changes in the length of a side of the structure when customizing; and a buffer portion that protrudes downward or laterally from the outer shell in the height direction to buffer external force.

[0017]

[0018] According to a customizable module according to one embodiment of the present invention, the problem of damage even when external force is concentrated on a specific part can be solved.

[0019] According to a customizable module according to one embodiment of the present invention, there is an advantage in that excessive deformation of a corner region of an outer skin defining a ventilation hole of a polyhedron can be prevented and external force can be reduced.

[0057]

[0058] In order to more clearly express the technical idea of ​​the present invention, the attached drawings have simplified or omitted parts that are not related to the technical idea of ​​the present invention or can be easily derived by those skilled in the art.

[0059]

[0060] Throughout the specification, when a part is said to be "connected" to another part, this includes not only the case where it is "directly connected" but also the case where it is "indirectly connected" with another component in between. Furthermore, when a part is said to "include" a component, this should be understood to mean that, unless specifically stated to the contrary, it may include other components rather than excluding them, and does not preclude the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0061]

[0062] First, to define the term for direction, when referring to FIGS. 2 to 6, the height direction may mean the up-down direction based on the cross-sectional view of FIG. 4, and the upper side in the height direction may mean the direction in contact with the user's skin, and the lower side in the height direction may mean the direction exposed to the outside.

[0063] On the other hand, when referring to FIGS. 7 to 9, the height direction may mean the up-down direction based on the cross-sectional view of FIG. 9, the upper side in the height direction may mean the direction exposed to the outside, and the lower side in the height direction may mean the direction in contact with the user's skin.

[0064] In addition, the lateral direction is a direction perpendicular to the height direction, and may mean the left and right directions based on the cross-sectional views of FIGS. 4 and 9.

[0065]

[0066] Hereinafter, a customizable module (10) according to one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 6.

[0067] For example, a customizable module (10) is a module (10) capable of plastic deformation at a predetermined temperature, and may be used as a cast applied to a wound, as in the publicly known KR 10-2249753 B1 (2021.05.03), KR 10-1909214 B1 (2018.10.11), and KR 10-1622883 B1 (2016.05.13), or may be used as a shin, joint, waist protector, or safety helmet, but there are no restrictions on the use.

[0068] Additionally, the customizable module (10) may be made of a curable resin, optionally rather than a thermoplastic resin, and may be cured after shape deformation.

[0069] However, for the convenience of explanation, the following explanation will assume that the shape deformation is thermoplastic.

[0070] For example, the customizable module (10) may be capable of plastic deformation when heated to a predetermined temperature higher than room temperature (for example, any temperature higher than 50°C).

[0071] For example, the above customizable module (10) may have a mesh shape that forms a ventilation hole (S) overall.

[0072]

[0073] The above customizable module (10) can be shaped and deformed through the ventilation hole (S) while heated to the predetermined temperature.

[0074] That is, since the plurality of above-mentioned vents (S) are each deformed into different shapes by an external force, the customizable module (10) can be shaped.

[0075] For example, the customizable module (10) may include a structure (support module, 100) comprising a thermoplastic material (which may be a curable material, as described above) and an outer shell (200) surrounding at least a portion of the structure (100).

[0076] For example, the structure (100) may be in a mesh shape to maintain its shape by resisting external force and form the ventilation hole (S).

[0077] For example, the above structure (100) may be a material whose main component is thermoplastic polycaprolactone.

[0078] For example, the outer shell (200) may be a mesh shape that covers at least a portion of the structure (100) to form the ventilation hole (S).

[0079] For example, the outer shell (200) may be made of an elastic material.

[0080] For example, the outer shell (200) may be a rubber or elastomer material having a predetermined elasticity, and at the predetermined temperature (for example, any one of temperatures higher than 50°C) at which the structure (100) is plastically deformed, there is no change in state and the structure may exhibit a unique elastic fluctuation.

[0081] For example, the customizable module (10) may further include a pad (P) made of foam in a portion that comes into contact with the user's body.

[0082] For example, the pad (P) may be stacked and placed on the upper side in the height direction of the outer shell (200) and may be attached to the outer shell (200).

[0083] For example, the above pad (P) forms a number of pores and has excellent cushioning properties, thereby reducing pressure applied to the body.

[0084] For example, the pad (P) may be in a mesh shape to form the ventilation hole (S), and the structure (100) may not undergo a state change at a predetermined temperature (for example, any one of temperatures higher than 50°C) at which plastic deformation occurs, and may maintain its own cushioning properties.

[0085] As a result, when the structure (100) is heated to the predetermined temperature (for example, a temperature higher than the melting point of the structure (100) and lower than the melting point of the outer shell (200), the state changes to a state in which plastic deformation is possible, and at this time, the outer shell (200) has an elastic material, so that the length of the structure (100) can be compensated for from being unintentionally greatly increased or the shape from being unintentionally greatly deformed, and also has the function of enclosing the structure (100) in a plastic state so that it does not flow out to the outside, and the customizable module (10) can be deformed into a shape as shown in FIG. 1 because the plurality of vents (S) are each deformed into different shapes by an external force.

[0086]

[0087] That is, to explain the process of customizing from the state of FIG. 2 to the state of FIG. 1 into a desired shape by the user, in the state of FIG. 2, the module (10) capable of customization is heated to the predetermined temperature to plasticize the structure (100), and then an external force is applied to change the shape of the mesh-shaped polygonal ventilation holes (S), so that the shape changes to a mesh structure having polygonal ventilation holes (S) of different shapes as in FIG. 1, and customization is performed.

[0088] After customization, the temperature of the customizable module (10) is lowered to recrystallize or harden the structure (100), and a custom structure (100) that maintains its shape by resisting external force is completed.

[0089] When a custom deformation occurs, the internal angle of the polygonal vent (S) changes, causing the vent (S) to be deformed, but the change in the length of the side of the polygon defining the vent (S) (the length of the side of the structure (100)) must be minimized.

[0090] If the length of the side is increased by an external force during the plasticization and custom deformation of the above customizable module (10), the cross-sectional area of ​​the side is reduced, and the strength of the above customizable module (10) is reduced, so that it cannot perform its function of supporting and resisting the external force.

[0091] Accordingly, the outer shell (200) and / or pad (P) having an elastic material allows the length of the polygonal side of the structure (100) to remain unchanged (or minimized) and only the inner angle of the ventilation hole (S) to change, thereby enabling customization and providing sufficient support.

[0092]

[0093] As described above, the user can easily shape-deform the customizable module (10) into a desired shape by applying an external force while the module is heated to the predetermined temperature, and when the structure (100) is cooled to room temperature in the deformed state, it hardens and can maintain the deformed shape by resisting the external force.

[0094] Meanwhile, in the case of the cast disclosed in the notices KR 10-2249753 B1 (2021.05.03), KR 10-1909214 B1 (2018.10.11), and KR 10-1622883 B1 (2016.05.13), there is a problem that the structure (100) is damaged (broken) when an external force is concentrated on a specific part.

[0095] For example, there is a problem that certain parts of the cast that come into contact with the heel or sole of the foot are damaged due to the concentrated load transmitted from the user through the heel or sole of the foot.

[0096] The present invention is a configuration for solving the above-mentioned problem, and with reference to FIGS. 2 to 4, the buffer unit (300) included in the customizable module (10) of the present invention will be described in detail below.

[0097] Fig. 4(a) is a cross-sectional view of a portion without the buffer part (300), meaning a cross-sectional view of the portion A-A' shown in Fig. 2, and Fig. 4(b) is a cross-sectional view of a portion with the buffer part (300), meaning a cross-sectional view of the portion B-B' shown in Fig. 3.

[0098] In addition, the ventilation hole (S) is assumed to have a square shape, and as a result, the outer shell (200) defining the ventilation hole (S) has four faces. For example, as illustrated in FIG. 3, the outer shell (200) may be composed of a first face (210), a second face (220) adjacent to the first face (210) and forming an angle, a third face (230) adjacent to the second face (220) and forming an angle, and a fourth face (240) adjacent to the third face (230) and the first face (210) and forming an angle.

[0099] That is, the first side (210) and the third side (230) may be non-adjacent, mutually facing sides, and the second side (220) and the fourth side (240) may be non-adjacent, mutually facing sides.

[0100] Here, as shown in FIGS. 2 to 4, the buffer portion (300) may be configured to protrude downward in the height direction from the outer shell (200) and buffer external force.

[0101] For example, the buffer part (300) may be made of an elastic material to buffer external force, and may be formed to protrude from the outer shell (200) in a direction lower in the height direction, that is, in a direction exposed to the outside rather than in a direction in contact with the user's skin.

[0102] As a result, when the customizable module (10) touches the ground or collides with an external object, the external force is not directly transmitted to the outer shell (200), but the shape of the buffer part (300) can be deformed to buffer the external force as it directly touches the ground or collides with an external object.

[0103] As a result, the buffer part (300) reduces the external force ultimately transmitted to the structure (100) by buffering the external force, thereby preventing damage to the structure (100).

[0104] Meanwhile, for example, the buffer portion (300) may be formed to protrude laterally from the outer shell (200), and further may be formed on the ventilation hole (S).

[0105] To explain this in more detail, when the buffer part (300) is formed to protrude and overlap with the structure (100) in the height direction from the outer shell (200), the possibility of the structure (100) being damaged increases as the vertical external force applied to the buffer part (300) is transmitted to the structure (100).

[0106] Accordingly, since the buffer part (300) is formed to protrude laterally from the outer shell (200) and is formed on the ventilation hole (S), there is a part that does not overlap with the structure (100) in the height direction, and thus the vertical external force applied to the buffer part (300) formed on the ventilation hole (S) is not transmitted to the structure (100), the possibility of the structure (100) being damaged is reduced.

[0107] The above buffer portion (300) can protrude only from one side of the outer shell (200) defining the ventilation hole (S) of the polyhedron.

[0108] To explain this in more detail, as shown in FIG. 3, four buffer parts (300) are formed on one of the above vent holes (S), and it can be seen that each of the four buffer parts (300) is formed to protrude from each of the first surface (210), the second surface (220), the third surface (230), and the fourth surface (240) of the outer shell (200).

[0109] If, assuming that one of the above protrusions is formed such that one end protrudes from the first face (210) and the other end protrudes from the second face (220) adjacent to the first face (210), when the shape of the customizable module (10) is deformed in a direction in which the angle formed by the first face (210) and the second face (220) increases, a problem may arise in which the protrusion prevents the shape from being deformed in the direction in which the angle formed by the first face (210) and the second face (220) increases.

[0110] Accordingly, since any one of the buffer portions (300) is formed to protrude only from one side of the outer shell (200), the customizable module (10) may not be prevented from undergoing a shape deformation (for example, in the direction in which the angle formed by the first side (210) and the second side (220) increases) through the ventilation hole (S).

[0111] Meanwhile, the buffer portion (300) can form an opening (A) that is opened in the height direction.

[0112] As a result, the buffer part (300) formed on the ventilation hole (S) can also maintain ventilation by forming the opening (A) in the height direction.

[0113] Meanwhile, for example, the buffer portion (300) may form a groove (not shown) that is recessed in the height direction.

[0114] Due to the above home, the weight of the buffer part (300) can be reduced, and further, the deformation rate of the buffer part (300) due to external force can be increased, thereby further improving the buffering performance.

[0115] Meanwhile, the buffer part (300) is made of the same material as the outer shell (200) and can be formed integrally with the outer shell (200).

[0116] That is, when the above-mentioned buffer part (300) is created (formed) on the above-mentioned structure (100), the above-mentioned outer shell (200) can be formed integrally with the outer shell (200) using the same material as the outer shell (200).

[0117] For example, when the outer shell (200) is formed on the structure (100) through insert injection or the like, the buffer portion (300) can also be formed at the same time.

[0118] Meanwhile, as shown in FIGS. 3 and 4, the buffer part (300) may include a first buffer part (310) that protrudes downwardly from the outer shell (200) in the height direction and overlaps at least a portion of the structure (100) in the height direction, and a second buffer part (320) that protrudes laterally from the first buffer part (310) and is formed on the ventilation hole (S) and protrudes downwardly from the outer shell (200) in the height direction.

[0119] For example, the first buffer part (310) and the second buffer part (320) can form the opening part (A).

[0120]

[0121] Below, another embodiment of the above buffer unit (300) will be described in detail.

[0122] Technical ideas that are identical to the buffer unit (300) described above or that can be easily inferred from the perspective of a person skilled in the art will be omitted or briefly explained.

[0123] First, referring to Fig. 5, a buffer part (300A) according to a first modified embodiment in which the buffer part (300) is modified will be described.

[0124] Fig. 5(a) is a schematic plan view of the buffer portion (300A), and Fig. 5(b) is a schematic cross-sectional view of the C-C' portion shown in Fig. 5(a).

[0125] As shown in Fig. 5, the buffer portion (300A) is also formed to protrude downwardly in the height direction from the outer shell (200), and can be formed to protrude laterally from the outer shell (200) and formed on the ventilation hole (S).

[0126] Here, the buffer portion (300A) can be formed by protruding from one side of the outer shell (200) defining the ventilation hole (S) of the polyhedron and another side that is not adjacent to the one side.

[0127] To explain this in more detail, as shown in FIG. 5, one end of the buffer part (300A) extends from the first surface (210) of the outer shell (200), and the other end of the buffer part (300A) extends from the third surface (230) of the outer shell (200), which is not adjacent to the first surface (210), and it can be seen that the buffer part (300A) is not connected to the second surface (220) and the fourth surface (240) of the outer shell (200).

[0128] As a result, the customizable module (10) may not be prevented from undergoing shape deformation (e.g., in the direction in which the angle formed by the first surface (210) and the second surface (220) increases) through the vent (S).

[0129] Meanwhile, the buffer portion (300A) may include a first buffer portion (310A) that protrudes laterally from the outer shell (200) but does not protrude downward in the height direction based on the outer shell (200), and a second buffer portion (320A) that extends from the first buffer portion (310A) and protrudes downward in the height direction from the outer shell (200).

[0130] For example, the second buffer portion (320A) may form the opening (A) or groove.

[0131]

[0132] In addition, with reference to FIG. 6, a buffer part (300B) according to a second modified embodiment in which the buffer part (300, 300A) is modified will be described.

[0133] Fig. 6(a) is a schematic plan view of the buffer portion (300B), and Fig. 6(b) is a schematic cross-sectional view of the D-D' portion shown in Fig. 6(a).

[0134] As shown in Fig. 6, the buffer portion (300B) is also formed to protrude downward in the height direction from the outer shell (200), and can be formed to protrude laterally from the outer shell (200) and formed on the ventilation hole (S).

[0135] Here, the buffer portion (300B) can protrude only from one side of the outer shell (200) defining the ventilation hole (S) of the polyhedron.

[0136] To explain this in more detail, as shown in FIG. 6, two buffer parts (300B) are formed on one of the above vent holes (S), and it can be seen that each of the two buffer parts (300B) is formed to protrude from the first surface (210) and the third surface (230) of the outer shell (200).

[0137] Accordingly, since any one of the buffer portions (300B) is formed to protrude only from one side of the outer shell (200), the customizable module (10) may not be prevented from undergoing shape deformation (for example, in the direction in which the angle formed by the first side (210) and the second side (220) increases) through the ventilation hole (S).

[0138] Additionally, the buffer portion (300B) can form the opening (A) or groove.

[0139]

[0140] Meanwhile, the buffer portion (300, 300A, 300B) described above may be formed by protruding only from one side of the outer shell (200) defining the ventilation hole (S) of the polyhedron, or by protruding from one side and another side that is not adjacent to the one side, but further, may not protrude from at least one side among the plurality of sides of the outer shell (200) defining the ventilation hole (S) of the polyhedron, and may protrude from the remaining side.

[0141] In addition, in the process of customizing the structure (100) from the state of FIG. 2 to the state of FIG. 1 into a desired shape by the user, the buffer unit (300, 300A, 300B) can prevent or minimize the cross-section of a specific part of the structure (100) from being crushed and reduced by buffering the external force / load generated when the customizable module (10) touches the ground or collides with an external object even when the structure (100) is in a plasticized state.

[0142]

[0143] As described above, according to the customizable module (10) according to one embodiment of the present invention, even if an external force is concentrated on a specific part, the problem of a specific part being damaged by the buffering of the buffer part (300, 300A, 300B) can be solved.

[0144]

[0145] Meanwhile, in the case of the casts disclosed in the notices KR 10-2249753 B1 (2021.05.03), KR 10-1909214 B1 (2018.10.11), and KR 10-1622883 B1 (2016.05.13), there is a problem that excessive deformation may occur in the corner area of ​​the outer skin defining the polyhedron's ventilation hole, and when applied to the affected area, the corner portion may touch the affected area due to three-dimensional distortion deformation, causing pain.

[0146] Hereinafter, with reference to FIGS. 7 to 9, a configuration for solving the above-described problem will be described in detail about a reduction unit (400), which is another feature of a customizable module (10) according to one embodiment of the present invention.

[0147] Fig. 9(a) is a cross-sectional view of a portion without the reduction portion (400), meaning a cross-sectional view of the portion A-A' shown in Fig. 7, and Fig. 9(b) is a cross-sectional view of a portion with the reduction portion (400), meaning a cross-sectional view of the portion B-B' shown in Fig. 8.

[0148] In addition, the above ventilation hole (S) is assumed to have a square shape, and as a result, the outer shell (200) defining the ventilation hole (S) has four faces.

[0149]

[0150] Here, as shown in FIGS. 7 to 9, the reduction portion (400) may be formed to protrude laterally from the outer shell (200) and may be configured to reduce external force.

[0151] For example, the above-mentioned reduction portion (400) may be made of an elastic material to reduce external force, and may mean a configuration in which it protrudes from the outer shell (200) in a lateral direction, that is, in a height direction that is not in contact with the user's skin or exposed to the outside.

[0152] As a result, when the corner portion of the customizable module (10) comes into contact with the user's skin due to a three-dimensionally twisted deformation, the reduction portion (400) comes into contact with the user's skin and reduces the external force, thereby reducing the external force transmitted to the user's skin.

[0153] Meanwhile, the above-mentioned reduction portion (400) may be formed to protrude laterally from the outer shell (200) and formed on the ventilation hole (S).

[0154] As a result, it is possible to secure an area for arranging the pad (P) which is stacked and arranged on the lower side in the height direction of the outer shell (200).

[0155]

[0156] Meanwhile, the above-mentioned reduction portion (400) can be formed in the corner area of ​​the outer shell (200) defining the ventilation hole (S) of the polyhedron.

[0157] To explain this in more detail, as illustrated in FIG. 8, in the four faces of the outer shell (200) defining the square-shaped ventilation hole (S), the reduction portion (400) can be formed in the corner area defined by the faces of the adjacent outer shell (200).

[0158] As a result, the reduction portion (400) can prevent excessive deformation in the direction in which the angle formed by the adjacent surfaces of the outer skin (200) increases and / or in the direction in which the angle decreases when the structure (100) is plastically deformed.

[0159]

[0160] Meanwhile, the above reduction unit (400) can form a reduction space (A).

[0161] For example, the above-mentioned reduction space (A) may be formed in the form of a groove on the above-mentioned reduction part (400), and the degree of deformation of the above-mentioned reduction part (400) due to an external force may be increased due to the above-mentioned reduction space (A), thereby reducing the external force transmitted to the user's skin.

[0162] Here, for example, the reduction space (A) may be a space open downward in the height direction.

[0163] That is, the above-mentioned reduction space (A) may be in the shape of a groove with an opening formed downward in the height direction in the direction in which it comes into contact with the user's skin, and as a result, the area in contact with the user's skin can be reduced, thereby increasing wearability.

[0164] Meanwhile, the above-mentioned reduction portion (400) is made of the same material as the above-mentioned outer shell (200) and can be formed integrally with the above-mentioned outer shell (200).

[0165] That is, when the above-mentioned reduction portion (400) creates (forms) the outer shell (200) on the above-mentioned structure (100), the above-mentioned reduction portion (400) can be formed integrally with the outer shell (200) using the same material as the outer shell (200).

[0166] For example, when the outer shell (200) is formed on the structure (100) through insert injection or the like, the reduction portion (400) can also be formed at the same time.

[0167]

[0168] Meanwhile, as shown in Fig. 9(b), the structure (100) may be formed with two surfaces (C1, C2) whose sides facing the reduction portion (400) form an obtuse angle in the area where the reduction portion (400) is formed.

[0169] To explain this in more detail, referring to Fig. 9(a), which is a cross-section of an area where the above-mentioned reduction portion (400) is not formed, it can be seen that the side of the structure (100) is formed of one surface.

[0170] On the other hand, referring to Fig. 9(b), which is a cross-section of the area where the reduction portion (400) is formed, it can be seen that in the cross-section of the structure (100), the side facing the reduction portion (400) is formed not as one surface but as two surfaces (C1, C2) forming an obtuse angle, so that the distance between the reduction space (A) of the reduction portion (400) and the structure (100) is formed relatively large.

[0171] As a result, the structure (100) can be prevented from being unintentionally exposed to the reduced space (A).

[0172] In addition, for example, when the outer shell (200) is formed on the structure (100) placed in the mold through insert injection, a guide pin (not shown) that contacts the inclined C2 surface formed on the structure (100) may be placed so that the structure (100) does not shake within the mold. As a result, the guide pin presses the inclined C2 surface formed on the structure (100) so that the structure (100) can be fixed at a desired position within the mold, and at the same time, the outer shell (200) can be formed through insert injection with the reduction portion (400) having the reduction space (A).

[0173]

[0174] Although the configuration and features of the present invention have been described above based on embodiments according to the present invention, the present invention is not limited thereto, and it is obvious to those skilled in the art that various changes or modifications can be made within the spirit and scope of the present invention, and therefore, it is made clear that such changes or modifications fall within the scope of the appended patent claims.
